Some of this is true but the strap mount I'm talking about was specifically designed for sat dishes with a special mount made just for the foot of DBS dishes. So would you understand that you have had problems with a bad mount on a chimney in the past and I'm telling about a mount that was designed to not do the things that you are talking about when mounting a dish. If you can't understand this we are to the point to agree to disagree. There has been another person that confirmed what I have said so please realize we are not atlking about the same kind of hardware. That what we are talking about was made to not damage the chimney.
